[Structure of the Bacillus brevis metalloprotease gene].
Primary structure of DNA fragment of 2355 b.p., encoding metalloprotease gene of Bac. brevis, had been determined. Open reading frame for a protein with size of 528 amino acid residues was found in this sequence. The encoding protein is homologous to metalloproteases of Bac. stearothermophilus, Bac. cereus, Bac. subtilis and Bac. amyloliquefaciens. The structure of Bac. brevis metalloprotease gene reveals that this enzyme is synthesised as pre-pro-protease with signal peptide and pro-region, which are cut during its synthesis. The proposed size of mature protease is 304 amino acid residues. The residues, essential for catalysis, binding of Zn ion and Ca ions were found on the basis of Bacilli metalloproteases structures comparison.
